Light Emitting Diode, commonly referred to as "LED" is a lighting technology that has come a long way in recent years when it comes to artificial Christmas trees.  The biggest problem with early iterations was that LED lights simply did not look like traditional mini lights! Many people prefer the soft, warm, and inviting look of an incandescent bulb.  This is why Treetime LED lighting uses a glass mini light bulb with an LED inside.  These LEDs burn at around 3000K (kelvin) which means the color temperature for clear lights is exactly like a regular mini light! Save up-to 95% energy use compared to traditional lighting but enjoy the same look.  All LED Treetime Christmas trees are rated at 25,000 hours of use, generate zero heat, and last nearly 10 times longer than standard lighting.
